Price of Civilization ~ Sachs on CNN re: "7 Billion"

CNN spots Columbia's Jeffrey Sachs on the Price of Civilization...

"...unless the world population stabilizes during the 21st century, the consequences for humanity could be grim. A rising population puts enormous pressures on a planet already plunging into environmental catastrophe. Providing food, clothing, shelter, and energy for 7 billion people is a task of startling complexity. [...] What will it take to maintain a planet in which each person has a chance for a full, productive and prosperous life, and in which the planet's resources are sustained for future generations? How, in short, can we enjoy "sustainable development" on a very crowded planet? The answer has two parts, and each portends a difficult journey over several decades. The first part requires a change of technologies -- in farming, energy, industry, transport and building -- so that each of us on average is putting less environmental stress on the planet. [...] The second key to sustainable development is the stabilization of the global population."
